Corten A steel

Product introduction

Corten A Weathering Steel
ASTM Corten A steel grade is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.The steel grade CortenA is according to ASTM standard which with the yield strength of 355MPa and the tensile strength of 470-630MPa.Corten-A steel was first used in buildings in 1958 because it has anti-corrosion properties. Then Corten-A especially in China and Japan was widely used for bridges, trains, cars, trucks and industrial facilities and so on.

The top layer of the material reacts with atmospheric elements to form a rust coloured protective layer which not only makes the steel virtually maintenance free but also provides a pleasing and consistent finish.
